12/10 – Rob Knight’s “Much Warmer” Mid-Morning Forecast
Dry high pressure at the surface will continue to dominate our weather today and much of Friday as the ridge slides east across Florida and the eastern U.S. coast region. Clear skies, calm winds and strong radiational cooling will result in areas of widespread dense fog overnight that will likely persist until around 9 am Friday. After the fog and associated low stratus clouds burn off, Friday afternoon clouds will be on the increase.
A potent disturbance over the Desert Southwest will push east into the mid-Mississippi Valley on Friday night. The associated cold front is expected to push east/southeast into Arklatex region Friday night and the central Gulf coast region on Saturday. This will bring increased rain chances area-wide Saturday morning before drier air ends the rain chances from the west Saturday afternoon and evening. A few embedded t-storms will also be possible.
A broad disturbance will move across the lower Mississippi Valley/central Gulf coast region Sunday afternoon and Sunday night. The anticipated drier conditions in the wake of the Saturday cold front will be short lived as the chance of showers and some thunderstorms will increase by Sunday afternoon and evening as a weak surface low pressure area and stronger cold front move through the region. Monday and Tuesday should be dry as a surface high-pressure will move across the north Gulf region.
